SOCIOECONOMIC GRADIENTS IN DEPRESSIVE SYMPTOMS AMONG OLDER ADULTS IN RURAL SOUTH AFRICA

Abstract Depression is one of the most common mental health disorders throughout the globe with an estimated 300 million people affected worldwide. Socioeconomic status may influence depression risk, due to its status as a critical influencing factor for health-related issues as well as serving as a barrier for healthy aging. The objective of this analysis was to examine the presence of socioeconomic gradients in depressive symptoms among older adults in Agincourt, a low-income rural region of South Africa. We conducted a cross-sectional analysis of baseline interview data from 2014/2015 for 5,059 participants aged ≥40 in the population-representative Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI). Household wealth was assessed as quintiles of an asset-based index, including ownership of assets such as housing materials, electricity, piped water, vehicles, and technological goods. Household per capita consumption on food, healthcare, leisure activities, and other goods was also assessed as quintiles. The presence of depressive symptoms was measured and categorized using the 8-item Center for Epidemiologic Studies Depression (CES-D) scale. We used multivariable adjusted logistic regression to examine the association between household wealth and household consumption quintiles and depression. In this study population, the prevalence of depressive symptoms was 17%. We observed no significant trends between household wealth, household consumption and depression (p=0.11 for both exposures). Depressive symptoms are not socioeconomically graded among older, rural South Africa adults. The high prevalence of depressive symptoms within the region should be considered as a public health concern.

that may affect the interactive behavior of Japanese older people were identified; (1) Japan's healthcare policy and pension system, (2) individual's socio-economic status, (3) family structure and living arrangement, (4) community's characteristics, (5) individual's psychological, cognitive and health status, and (7) individual's personality.Comparisons of social interactions between Japanese and US older adults will be important to find new knowledge for preventing social isolation.

Nagasaki University,Nagasaki,Nagasaki,Japan Objectives: This study aimed to examine whether facing obstacles between work and care provision (work/ care obstacles) is a risk factor for life satisfaction and explore whether it moderates the association between care burden and life satisfaction among Japanese working family caregivers.Methods: This cross-sectional study was conducted on 141 working family caregivers aged less than 65 years who were living with an older care recipient.We fit a multiple logistic regression model to examine the main and moderating effect of work/care obstacles on life satisfaction, in the context of care burdens.Results: Facing work/care obstacles had a main effect on life satisfaction among employed family caregivers.Furthermore, work/ care obstacles exacerbated the association between caregiver burden and life satisfaction.As for the family caregivers who did not experience work/care obstacles, the risk of poor life satisfaction did not differ regardless of number of caregiver burdens.In contrary, the family caregivers who experienced work/care obstacles and had 2 or more caregiver burdens had a poor life satisfaction (odds rations = 5.5, 95% confidence intervals = [1.97,15.43]) compared with those who had 1 or less caregiver burden.Conclusion: These findings suggest that obstacles between work and family was a risk factor for poor life satisfaction for employed individuals in Japan caring for an older relative.Mitigating such obstacles may be important for job retention, given the growing number of older adults in Japan.Key words Facing obstacles between work and care provision, family caregiver, life satisfaction, well-being, work-life adaptation Abstract citation ID: igad104.3054

THE LIFESTYLE OF MEN AND WOMEN AGED 50+ IN TAIWAN: ACTIVITY ON TIME OF DAY AND THEIR CIRCADIAN RHYTHMS
Ching-Ju Chiu, National Cheng Kung University, Tainan City, Tainan, Taiwan (Republic of China) Background: To identify the association of circadian rhythms and objective measures of physical activity at a different time-zone of day, as well as examine gender differences.Methods: Participants aged 50 years and older living in the community in Taiwan were recruited.Those who suffer from dementia (cognitive dysfunction), mental illness, depression, or those taking drugs that affect daytime activities (e.g.sleeping pills, central nervous system drugs) were excluded.Activity was measured by wearable actigraphy device for at least seven days, diary, and self-reported questionnaires.Results: Among the 55 participants enrolled in the beginning, 34 (62%) meet the criteria that wore a wearable actigraphy device at least 7 completed days were analyzed.The activity in the morning was the highest among the participants.Although not statistically significant, as the age increases, the amount of activity decreases (H value=4.943,P=0.084); the amount of activity in the evening is higher for people with higher education(Z=-1.776,P=0.076); people with lower loneliness had higher activity levels (Z=-1.622,P=0.105); people with better nutritional status had higher activity (Z=-1.656,P=0.098).The amount of activity in women is positively and significantly related to regular exercise (Z=-2.653,P=0.007**), and nutrition(Z=-2.367,P=0.017*), while men are significantly related to retired status(Z=-2.132,P=0.033*).Conclusions: People who are older, retired, with chronic disease, more depression, and loneliness were associated with lower objective measure of physical activity.Determinant factors exist gender differences: while men are predicted by social variables (retired status), women are predicted by physiological variables (regular physical activity and nutritional status).

THE ROLES OF COLATEC SOCIAL DANCING IN HEALTHY AGING AMONG KOREAN OLDER ADULTS
Milae Lee, Xingxing Wu, and Laura Payne, University of Illinois Urbana-Champaign, Champaign, Illinois, United States Leisure activities can contribute to healthy aging (An et al., 2022).However, little research exists on leisure activities with soft stigma (Kraus, 2010).Yet, social dancing in Colatec (i.e., Korean daytime discos for older adults) is becoming more popular among older Koreans.Using qualitative methods, we examined how Colatec social dancing affects Korean older adults' healthy aging.Thirteen participants aged 60 to 75 who regularly social dance at Colatecs voluntarily participated in an in-depth semi-structured interview that lasted between 45 to 75 minutes.The audiotaped interviews were transcribed verbatim, coded, and analyzed following interpretive phenomenological analysis (Smith & Osborn, 2003).Trustworthiness was assessed with member checking and researcher triangulation.Results revealed that although it is still culturally stigmatized, Colatec social dancing was essential for participants' healthy aging.Participants perceived numerous benefits from social dancing that motivated their enduring engagement, despite the risks of the social stigma associated with Colatec dancing.Themes that emerged included: 1) Exercise from social dancing alleviated stress and depressive feelings associated with negative life events; 2) Colatec dancing boosted many participants' self-esteem, enhancing their overall wellbeing; and 3) Meaningful social connections were developed among participants.Findings align with existing literature on how moderate physical activity contributes to older adults' health (Bauman et al., 2016).Moreover, leisure serves as a social lubricant and enhances healthy aging (Mitas et al., 2011).Lastly, perceived by participants as a "playground", Colatec affords older Koreans a space for engaging leisure activity which facilitated their healthy aging process (Heo et al., 2018).
